Specification o! Lett'erl Patent. Application and June 14, 1007. s nd No. 319,002.

, Patented March e1, 1908.

To allwhom 'it may concern:

Be it known that I, JENNINGS S'oo'r'r Mo- Westchester and State of New York, have invented certain new and useful Improvements in Desks, of, which the following is a specification, reference being had to the accom anymg drawin 1s invention re ates to desks and especially to roll-top oflice desks which I ada t for book-keeping ur oses by supporting t e flexible cover. of t e esk at the pro ere evation to form a supplemental bookeeperss table.

In the accompanying drawings showin illustrative forms of this invention, in whic the same reference numeral refers to similar transverse vertical section taken through an ordinary roll-top desk showing my invention applied thereto. Fig. 2 is a transverse vertlcal section similar to Fi 1 showing the flexible cover of the desk e evated to form a supplemental table. Fig. 3 is a vertical cross-section taken on the line 33 of Fig. 1.

In the illustrative embodiment of this invention shown in the drawings, 1 is an ordinary roll-top desk having pigeon holes 2, 2, 2, a top 3, side pieces 4, 4, cap 5, flexible cover 6, and curved passages 8, 8 for the flexible cover 6 when in its rearward or in- Though I have only own one side piece 4, i'tis tobe understoo of course, that each desk has two such side pieces and therefore only one will be described, the other being a counterpart of it.

Each side piece has the ordinary oove or guide 9, Fi s. 2 and 3, within whic slide the ends 'of t e slats forming the flexible cover 6. I preferabl form each side piece 4 into two parts an make one portion or support 10 movable, with relation to the main portion of the side 'piece 4, by hinging it at 11. Within the support 10 hes a considerable portion of the guide 9 within which slide the ends of the slats 12 which are preferably mounted upon the fabric or other backing 13 to form the flexible cover 6.

When the desk is to be used in the ordinary manner, the cover 6 merely acting to close the desk, the support 10 lies in the cut-out ortion 14 of the side 4 and is referabl ocked' in this position by means oi the hoo 15 mounted upon the side piece 4 cooperating with the pin 16 carried by the movable course, understood that the cover 6 is either in the curved passages 8, 8 before the supports 10, 10 are elevated, or that the cover 6 as atleast been elevated sufficiently to permit its end 17 to be flush with the surface 18 at'the extreme end of the su port 10.

The table or support 10 is held it its elevated position by means of a leg 19 pivoted at one end at 20 within the rabbeted portion '21 of the side 4, its other end having a reduced portion 22 adapted to fit in an open-v ing in the plate 23 carried at the lower end of the support 10.

To ernnt of the flexible cover performing its or inary function of closing the desk it is merely necessary to reverse the operation of the parts by withdrawing the end 22 of the leg 19 from the hole in the plate 23 and fold it 1n'to its rabbeted seat 2 1, ermitting the support 10 to move upon its lugs 11, bringing the different portions of the groove 9 lntoalinement when the flexible cover 6 can be either pushed back into the curved passages 8, 8 or further extended to close the desk in the ordinary manner.

By my invention I am enabled to convert an ordinary roll-top desk into a bOOk-kP PP'. ers desk in a few seconds. My invention furthermore is inex ensive and canbe applied to any roll-top des now in use. Having thus described this invention in connection with the several illustrative embodiments thereof, to the details of which it is not of course to be limited, what is claimed as new and what is desired to be secured by Letters Patent is set forth in the appended claims.

1. A roll-top desk having the ordinary flexible cover and curved guides, side pieces the ordinary being movable relativelyto each being formed intwo arts,

e other, and a leg to support the movable part im its elevated position.

3. A roll-top desk having the ordinary flexible cover and curved guides, side pieces each formed in two parts and pivotall connected together, one portion of eac side piece having a rabbeted seat for the reception of a pivoted leg to be concealed therein,

vflexible cover and curved guides, side pieces each formed in two parts and pivotall connected together one portion of eac side piece having a rabbeted seat for the reception of a pivoted leg to be OOIICGiLlGd'lZhGIGlI].

a leg pivoted to said side piece and mounted .within said seat and adapted to support the movable part of the side piece in elevated one part positionfand means to lock the parts of the two side ieces to ether.

5. A r0 -top des having a flexible cover, side-pieces each having a guiding groove having a. substantially straight portion to 006 erate with the ends of the flexible cover in c osing the desk, each of said side pieces having a movably mounted part comprising the straight portion of said guiding groove, and a leg to support the movable part in elevated position. 6. A roll-top desk havinga flexible cover, side-pieces each having a guiding groove to cooperate with the ends of the flexible cover in regularly closing the desk, each of said side-pieces having a movable part comprismg a portion of "said guidin groove, and

means to support the movab e part in elevated position.
